Thanks Scott - I will be checking out the tutorial.
Yeah, you would think they could be a little more sophisticated with the passing car thing - at least only have them passing when a slower vehicle is in front, not just randomly passing ghost cars no one else sees! But I would be perfectly happy NOT to have them lane change like that. It's called "Trainz," not "Carz," and from the perspective of the train, the lack of realism from not changing lanes would be far less noticeable than head-on collisions passing right through each other.
I also agree that there ought to be a way of controlling what kinds of vehicles appear where. Maybe have road spline types that spawn only cars, only trucks, only a mix? I don't know enough about the back end of things to know if that's possible?
While I'm griping, how about "smart" intersections with traffic lights and "stoppable" traffic? I know there are some great working intersection "kits" but they're a pain to set up. How about something you just drop in position, connect up the roads, and it just works? Yeah, yeah, it's easy for me to say...I don't have to make the things!
I haven't tried it yet in 2012, but in 2009 the L-shape turns wouldn't carry the cars around them, so they'd just disappear. Again, I know this is "Trainz," not "Carz," and I can live without high realism on the roads (I'd rather out those resources into the train realism), but there are a couple things like that which are obvious and sort of ruin an otherwise cool effect. Nothing worse than spending hours creating a detailed layout only to have it spoiled by seeing a vanishing car outside your locomotive window!
Thanks guys!
